Your Style. Our Precision.
The HPVM is the most versatile graphing volt meter available today. Accurate to 1/500 of a volt and capable of measuring two sources simultaneously, the HPVM comes equipped with Bluetooth connectivity, allowing it to connect to the free Aural Sync™ app, optional AuralSync Companion Smartwatch, and other AuralSync-enabled devices.
Use the app to choose any one of ten gauge designs, then create user-definable voltage ranges and custom colors to make each look match your needs, and your style.
Overbuilt To Last
Extremes in vibration, humidity, and temperatures are always attacking everything in your vehicle. A solid aluminum case houses high-density/temperature internal supports, and gold-plated ENIG PCB to survive – and thrive – in any build.
Maximum Battery Efficiency
To save your battery power, the HPVM is equipped with Deep Sleep mode. When a gradual voltage drop with no transients is detected, the meter automatically reduces power consumption to just 167 milliwatts. At that rate, it would take 7,059 hours (294 days) to fully drain a 100 amp hour 12V AGM battery.
Once the meter detects a voltage spike, it instantly returns to full operation. It will also display total battery drain during low-power mode and issue a bright red warning if the voltage drop was significant, signaling a weak battery or excessive parasitic draw.

I give the quality volt meter a 5 star rating with out testing it. Only by handling out of package. Great job guys. Very nice product and another 5 star after powering it on. JEREMY S
One of the best if not the best volt meters out in the market. The software works flawlessly And measures very accurately. I love the customization that you can do with this meter unlike others .
Love my meter. Very accurate!
I will never be able to use any other meter ever again I thought I was charging at a higher voltage then I am I also thought I was dropping to a lower voltage then I am by almost a full volt so the accuracy and speed are amazing and his other products coming are true game changers
This volt meter is incredibly accurate. There's so many functions on the app to make the meter even cooler! I highly recommend this item if you care about your audio equipment and batterys. Very simple to install instructions are pretty straightforward
